摘要：本文根据排山楼金矿采空区稳定到亚稳定的现状,以及地表尾矿库需要保护程度的要求,提出留“L”字形保安矿柱和从地表打井分区充填采空区的综合治理方案.其中北侧空区稳定性较好,用VCR法从地表掘井后,用废石充填十碎石混凝土接顶.南侧空区目前处于亚稳定状态,采取钻孔监控下逐步充填方案,即从稳定性较好部位向稳定性较差部位依次打井充填.在充填井的施工与充填过程中,用钻孔监测空区冒落状况,建立报警系统,确保施工安全.此外,对于南侧空区,还考虑了一旦冒透地表后的散体充填黄泥的防渗处理预案.目前该方案正在实施中,其中北侧空区已用VCR法凿井42m.初步实施效果与分析表明,上述监控充填方案,能够较好地适应空区围岩的稳定状态,可使空区得到安全、经济、高效治理.%In this paper, according to the present situation of mined-out area stability in Ppaishanlou gold mine, which is from stable to low stable, and the requirements of guarding surfical tailings reservoir, we put forward a comprehensive treatment plan, that is, remaining safety pillars in underground production work face and filling the mined out area by the filling well from the surface. The filling well is excavated by means of VCR technique, drilling holes and blasting in section. The waste rocks and gravel concrete are chosen as the fill material, the former is the main filling material and the latter is used to contact the roof. Relatively, in the north side, because of the better stability of surrounding rocks, making well and filling activities are operated normally. However, in the south side, the gradual filling method is applied due to lower stable state of mined-out areas, namely the filling step by step from better stable areas to less. In the whole process of building wells and filling them, the falling situation of mine-out roof is monitored by drilling holes and an alarm system is established for safety of production work. Besides, a preplan is designed to use yellow mud to fill loose body to form an anti-seepage layer in case of mine-out roof caving to surface. At present, the method is in production and a filling well has been excavated 42 meters by VCR technique. It was proved by the effect of excavated well and theory analysis that this method could adapt to the stability of surrounding rocks of the mine-out areas and a safe, economic and high efficient treatment result of the mine-out area could be reached.
